enter :when the rake bar is elevated so that -the rakehead will be swunginwardly or ways-are formed in an enlarged portion of g .the rake barat. the lower end ofthe latter l.and immediately kabove the rake head'ligas' [clearly illustrated v in the drawings- The ,rollers 25, 26 areso disposed thatthejrake bar issnbstantially parallel with the rack 2-and since the guideways 20, 2l are parallel with each other the rake barwill travel in a plane f substantially parallel with the rack 2 with theteeth 19 of the Vrakehead projecting between theslats of the rack; butin' order to'4 throw the rake head outwardly` 4away from the rack, whenit is being lowered, we

provide, at the lower end of the channel 20,v

a pivoted deilecting plate or member 31 which'Iservesto throwl theroller 26 out of the upper'end of the channel 29 and conse-v quently tothrow the rake head outwardly or forwardly so that the roller 26 willen-vl gage the outer face of the rib or flange 22 when the rake barmoves downwardly. The upper end of the channel 2O is provided with aninlet 32 which is adapted to permit 'the roller- 26 to return to saidchannel 20 and which is formed by slitting the flange or rib 4,22andubending it outwardly to provide the inclined or cam portion 33., Itwill be seen that when the rake bar lowers and the ineline 33 passesbeneath the roller 26 the rake head will be permitted to swing inwardlyi against the rack and when the rake bar is again raised the roller 26will pass through` the inlet 32and .into the channel- 20. The

deiiector plateBl'is vpivoted at its upper end,

as at 34,' and actuated by a spring 35 so that igtslowery end engages arecess or seat in the rib or ,a/nge 28, as seen in Fig. 5.

The rake is Araised and lowered by a cable or thelike 36`o'ne end ofwhich is attached I to and wound upon the winding drum or win'dlass 10and the other endof which is attached to the lower end of the rake bar.The intermediate portion of said cable passes over a guide pulley 37journaled between the inner portions ot the arms 14 andV also over aguide roller 38 arranged in a guard plate 39 which is disposedvimmediately above the upper end of the lrackl 2 and is attached to theouter edge of the trough 7, as

seen in Fig. 1.

4:0 denotesfa spring arranged between the arms .la and adapted to becompressed by the rake bar as the head` of -the' latter is movedinwardly to discharge its contents into the trough 7 and also adapted tothrow the rake hea-d outwardly the instant the hoisting cable is'released.

4l denotes a guard which .prevents the carriage from tilting. It islinthe form` of a bracket attached to the platform 8 of the portions,

, carriage and having its lower end projecting .n

under the head ot one of the track rails 4', as` seen in F ig. 1. ,i

-In tiperation, when the carriage is placed jupon the track the boom orrake support-t) iis adjusted to properly position the plates l5 abovethe rake, 'a'iidqthfe bearing blocks 27 are then adjusted so that, whenthe rollers 2h are in the guide channels 20 the rake bar will besubstantially parallel with the rack. When the parts are in the positionshown in Fig. l and the drum l0 is rotated to wind the cable thereon,the rake head will be moved vertically'and the rake bar will travel in aplane parallel with the rack 2-until the rollers 26, 25 enter theportions 29, 30 of said guide' channels, whereupon the'ralre head willbe swung inwardly to throw the trash upon it into lthe trough 7. Whenthe rake bar is thusl swung it will compress the spring Zl0 so that theinstant the cable is released said spring will swing kthe .rake headontwardly and the vrake bar will be permitted to drop by gravity. As thelower end of the rake bar swings outwardly the rollers 2li are deflectedby the plates 31 out of the lower ends of the channels so that they willtravel upon the outer acesof the {langes or ribs .22, thereby holdingthe rake head away from the -rack until said rollers again enter thechannels'20 at the upper ends of the lat ter. After one portion of therack 2 has been cleaned the carriage. may be adjusted to clean anotherportion oi the sinne, but it will. be understood that the cleaningdevice may be mounted stationarywhen the rake head can be madesuiiiciently broad to clean the entire rack at one o eration.
